STANDING-VALVE LIFTER.

Application led June 6, 19x27. Serial No. 196,764.

In' pumping deep wells suchas oil wells, the standing valve rests on a tapered seat and becomes thoroughly liXed in this seat due to the weight of the fluid, sand, and various other causes. When it is desired to remove the standing valve, suitable means arek proy 6v and a square block 101s threaded to receive vided whereby the plunger engages the valve which is then pulled out` by pulling on the suckerrods. Dueto the fact that the standing valve issecurely fastened `in its seat, a Vsevere strain is placed on'the sucker rods which tends to stretch them and so materially weaken the various rods that they'will break, either at the time of pulling or later during the pumping operations and 'this results in a tedious iishing job. f VAn Aobject of our invention is to provide a novel means of lifting the standing .valve from its seat so that it may be readily renioved.-

Stillanother object is to provide a vstanding valvelifter which may be used in conjunction with any well-known type of standing valve puller and which is operated by the rotation of the sticker rods.

A further object is to provide a. standing valve lifter which is simple in construction and effective in operation.

Other objects, advantages, and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing:

Fig. 1 is a longitudinal sectional View of the well tubing'with our lifter in position therein.

Fig. 2 is a longitudinal sectional view of our lifter.

Fig. 3 is a sectional view taken on line 3, 3 of Fig. 2.

Referring more par ing: Y

The well tubing 1 has depending from the ticularly to the drawbottom thereof a tube 2 ontlie bottom of which tube is provided ashoe 3 in which the 'standing valve et is seat-ed. It is evident that the tubing 1 may extend down to the shoe 3, or the shoeV may be entirely dispensed with and the bottom vof the tubing suitably taperedv to provide a seat for the standing valve.

This construction is all well-known and usual in the industry.

The standing valve 4 is of usual and welll y the lower end of a guide 6,- which guide is f known and iii comnionuselA A flangev 12 isfoijmed on the .postj9 squarein'cross-section, the purpose of which will'be further described.; Arcage 7 rests on a shoulderfSin the tubing, which shoulder may be the top of the tube 2, or it lmay be formed directly within the tubingvl.

A threaded postv 9 extends into they guilde a pair of fingers, as shown, or a threaded pin,

or any other suitable type such asare well- F and the cage l is mounted between the puller 11 and flange 12, said cage being freelyrotatable on the post. vA nut 13 on the bottom of the post 9 prevents the ,blocklO from screwing o? of y 'l said post. the top thereof, and bleed holes 15 extend into the bore so that water, sand, andsoforth, can

drain from the guide 6.

In operation the -ro'd y5 is tightly 'screwed' vo nto the standing valve 4; and the guide 6 is tightly'screwed onto the rod, thus the guide, rod, and standing. valve are nonrotatably held since the standing valve is tightly sealed in the shoe 3. The plunger 16 is provided with suitable means, such as the bayonet joint' 17 'for engaging the puller 11. The plunger is lowered to engage the puller when it is The rod 5 isbored, as lat 14, in

desired to remove the standing valve and is Y l then rotated, screwing the post 9 into the block l0, and thus causing the block to move up-y wardly on the post pulling the standing valve from its seat, after which the plunger and :puller assembly kare all removed from the well without .any strain on the rods.

Then the standing valve 4 is returnedinto the hole and it is necessary to get oil of the puller 11 with the plunger 16, the standing valve must be `held against rotation. rFor this purpose we provide lugs 1 8fon the lower end vof the standing valve 4, which lugsengage proiections 19 on the inside of the shoe 3, thus holding the standing valve against'rotation.Y

Of course, atterthe valve has been in use'for a considerable length of timeit will be thoroughly seated and the lugs 18 are of no value, except during the time th at the standing valve is lirst being placed in position.

Having described our invention, we claim:

1. In a well including a standing valve and a plunger, pullerfmeanson the plungeiga cage seated in the well tubing, athreadedpost eX- tending through ysaid cage, means` on said' `on rotation' 'of said post.

y said post adapted to be engaged by saidpuller means whereby s aid post may be rotated to lift the standing valve;

l 3, In a well including a standing-Valve and a plunger, aioage seated in the well tubing, a threaded rod rotatably mounted in the cage,

aguideseeured tothe standing'valye, a block non-rotatably and slidably mounted insaid guide, said post 'being threaded through the block whereby the standing Valve is lifted 4. Ina well including` a standingvalye and rr`a'lpluiiger, puller means on theV plunger, a cage seated in the well tubing, a threaded post extending through said eage, means on said postv adapted tol be rengaged by said puller means, and means secured to said standing valve andto said post whereby the standing valve is lifted when said post is rotated, and

cage seated in the well tubing, a threaded post Y extending through said cage, means on said pest adapted to be engaged by said puller means, and means secured to said standing Valve and to said post whereby the standing valve isli'fted when said post is rotatedfand means non-rotatably holding said standing valve when seated in the well, 'said holding means 'for the standing `valve including` lugs projecting from the standing Valve, and pro jeetions on the seat vadapted to be engaged by said lugs y.to hold the standing valve against y rotation. f i `puller means on the plunger, means on said rod. adapted to be engaged by the puller means,

6; In a well ineludinga plunger, a standing Valve seated therein, a rod secured to said standing valve, a guide seeu'red to said rod, a cage seated in the' well tubing, a threaded vpost rotatably mounted in theeage'and depending therefrom, a block non-rotatably held in said guide through which said rod Ais threaded, puller means onthe plunger, andy means on the rod VVadapted to be engaged by said puller means whereby said rod is rotated to lift the standing valve.
